Thanks!

Yes, they are correct.
There are some differences if you use them in other type of routes.
For example in onsend_routes and branch routes, only the set_forward*
 work and they will apply only to the current message / current branch.

E.g.:
onsend_route{
    if(to_ip!=10.0.0.0/8){
        #only reuse connection for IPs outside the local net
        set_foward_no_connect();
    }
}

In a reply route they will apply only to the current reply (so you will
see their effect only if the current reply "wins" and it's forwarded).


As you said set_*_close() must be used with care (and in general they
should be avoided). Especially dangerous is the combination of
set_*_close() and set_*_no_connect() (it works only once, after that no
further messages can be forwarded to the same destination).
The primary purpose of set_*_close() is for xmlrpc use (work around
against the python xmlrpc client bug).

Yes, they work with TLS. They don't work yet with SCTP (but I'll add
support for them to SCTP later).

Nothing, they are ignored.
